COCK OR VALVE.

sPEcIFIcATIoN forming paie of Letters Patent No. 263,091, dated August 22, 1882.

Application filed March 20, 1882. (No model.)

To all whom it may concern Be it known that we, DAVID REGINALD ASHTON and JAMES NEVILLE SPEERYN, subjects ofthe Queen of Great Britain, residing respectively at Clapton, in the county of Middlesex, and Brixton Hill, in the county of Surrey, both in England, have invented certain new and useful Improvements in Cocks and Valves, (which has not been patented to them, nor to others with their knowledge and consent, in any country,) of which the following is a specification.

Our invention relates to improvements in bib-cocks, stop-cocks, ball-cocks, and other cocks or valves for controlling the passage of gas, steam, water, and other fluids.

The invention consists in the peculiar construction and arrangement of parts, as hereinafter fully described.

Figure l is a side elevation of my improved cock. Fig. 2 is a central longitudinal section of the same. Fig. 3 is a detail view, partly in section. Figs. 4 and 5 are sectional views of modifications of the invention. v

c is the body, of any suitable form, and having the inlet and outlet in any convenient position relatively to the valve and valve-seat, according to the purpose for which the cock or valve is intended.

b is the barrel portion of thc body, cast in one therewith, through which the valve-spindle passes axially, the barrel being large enough to permit of the valve passing through it.

c is the valve, preferably of the usual disk form, orit might be conical, and closing down upon a corresponding seat form ed in the body a, as usual.

4 d is the valve-spindle, and e is a cupped plunger or piston, of metal, leather, india-rubber, vegetable ber, or other suitable material, xed upon the spindle d, this plunger or piston fitting in the barrel b and moving up and down therein with the spindle cl. The plunger e is secured upon thespindle d, as shown in section in Fig. 3, between a shoulder, d', formed on the spindle, and a nut, d2, screwed upon a part, (la, and forming a head for the spindle, between which and the shoulder d' the plunger is tightly clamped. The barrel b is turned true internally and the plunger fits accurately therein.

fis a cap inclosing theA top of the barrel b, and formed with aquick, coarse, internal screwthread, which works upon a corresponding screw-thread cut upon the exterior of the barrel l). I

g is a set-screw in the cap, the point of which comes under an external shoulder on the barrel to prevent the cap being unscrewed too far. The cap is provided with a cross-handle, h, by which it is turned; but it might be a knob or a wheel-handle; or, in the case ot' a ballcock, the ball-arm would take its place and the axis of the valve would be horizontal instead of vertical.

In Figs. l and 2 the cup fis wholly separate from the spindle e and merely presses upon the top of the spindle in order to force the valve down upon its seat, the valve being intended to be raised off its seat by the pressure of the tluid alone. Fig. 4 shows a precisely-similar cock, exceptA that the spindle is provided with an extension, i', which enters loosely a hole in the cap, and has a neck or groove, j, at its upper end, in whichthe point of a Set-screw, k, in the handle is received, in order to so far connect the cap to the spindle that, although the former turns independently of the latter, as before, the valve will be raised off its seat by the cap when it is unscrewed, instead of by the duid-pressure, as before.

Instead of the groove j and set-screw 7c, the

part t of the spindle might be continued quite through the handle and have a nut upon it above the handle.

Fig. 5 shows a cock differing only from that shown in Fig. 1 in the position of the valve and screw-cap relatively to the inlet and outlet, the term screw down77 being herein intended to include a screwing in any direction.

Having described the nature of the said invention and the manner of performing thev same, I declare that what I claim isl. The combination, with the body a, provided with the externally-screw-threaded barrel b 4and the internally-serew-thrcaded cap 2 Maen f, of the Valve-spindle d, provided with the shoulder ofthe valve-spindle, substantially as io shoulder d and the serew-threaded extension aud for tlie purpose set forth.

d3, the cup-shaped plunger e, rest-ing ou said DAVID BEGIN-ALD ASHTON shoulder, and nut cl2, substantially as and for JAMES NFVILLE SPERRYN 5 the purpose set forth. J

2. The combination, with the Valve-spindle Witnesses: d, provided with the shoulder d and the 4JJNO. DEAN, screw-threaded extension cl3, and the nut d2, H. E. DALE, of the Cupshaped plunger c, resting upon the Both of 17 Gracechurch S., London, E. C.
